NAME

JSON::Schema::Modern::Error - Contains a single error from a JSON Schema evaluation

VERSION

version 0.575

SYNOPSIS

  use JSON::Schema::Modern;
  my $js = JSON::Schema::Modern->new;
  my $result = $js->evaluate($data, $schema);
  my @errors = $result->errors;

  my $message = $errors[0]->error;
  my $instance_location = $errors[0]->instance_location;

  my $errors_encoded = encode_json(\@errors);

DESCRIPTION

An instance of this class holds one error from evaluating a JSON Schema with JSON::Schema::Modern.

ATTRIBUTES

keyword

The keyword that produced the error; might be undef.

instance_location

The path in the instance where the error occurred; encoded as per the JSON Pointer specification (RFC 6901).

keyword_location

The schema path taken during evaluation to arrive at the error; encoded as per the JSON Pointer specification (RFC 6901).

absolute_keyword_location

The canonical URI or URI reference of the location in the schema where the error occurred; not defined, if there is no base URI for the schema and no $ref was followed. Note that this is not a fragmentless URI in most cases, as the indicated error will occur at a path below the position where the most recent identifier had been declared in the schema. Further, if the schema never declared an absolute base URI (containing a scheme), this URI won't be absolute either.

error

The actual error string.

exception

Indicates the error's severity is sufficient to stop evaluation.

METHODS

TO_JSON

Returns a data structure suitable for serialization. Corresponds to one output unit as specified in https://json-schema.org/draft/2019-09/json-schema-core.html#rfc.section.10.4.2 and https://json-schema.org/draft/2019-09/output/schema, except that instanceLocation and keywordLocation are JSON pointers, not URI fragments. (See the strict_basic "output_format" in JSON::Schema::Modern if the distinction is important to you.)

dump

Returns a JSON string representing the error object, according to the specification.
